Know Your Curbs: Types Of Curbs And Its Significance

Curbs are an important element of road construction and serve several purposes. From defining a limit between the carriageway and pavement to containing it to prevent spreading curbs, there are several reasons why curbs are incorporated into the road.

One of the main reasons behind the application of the curbs is creating a barrier between vehicles and pedestrians to make the mode of walking and driving safer.

Moreover, the curbs help the driver and the pedestrian cross the abstraction boundary and provide a physical check to prevent vehicles from leaving the carriageway.

With such an important role, it becomes rather necessary to know more about the little slab of concrete that has been saving our lives for a long time.

Different Types Of Curbs:

The best way to understand the function of curbs is by first categorizing them according to their structural composition. While the application of the curb created by the Concrete Paving Machine remains the same, there are different variations available.

Though usually curbs were laid down using natural stone, it has been supplanted by precast concrete nowadays. Some of the basic curb profiles used for construction are half-battered, bull-nosed, splayed, and square.

Depending on the regulation of the place, the length of the curb may vary. However, most straight curbs go as lengthy as 915 mm, while the radius curbs are usually 780 mm in length.

●        Extruded Curbs

Extruded curb edging is one of the most commonly planted curbs. They are normally used on long and straight roads such as motorways, highways, and carriageways. These types of extruded curbs are laid down using a laying machine.

The Curb is first formed using concrete or asphalt bonded materials to the strength. The existing asphalt surface. Moreover, the concrete curb can be laid using a slip-form Curbing Machine to continue developing the curbs along the road.

●        Natural Stone

Granite is one of the most sought-after choices to make curbs. However, to the mixture, gabbro, basalt, and sandstorm may be utilized. Moreover, natural stone has a higher durability rate despite being an expensive option. Though mending or maintaining the curbs made out of natural stone may be an issue, it sure will last a lifetime.

●        Precast Concrete

Precast curbs are one of the most common choices for making curbs along the road as they are very strong, comparatively durable, and relatively cheaper than natural stone. If you want to achieve the same effect as the natural stone at a cheaper rate, this is what you should go with. The concrete can be made under strict tolerance to meet the requirements.

Ending note:

Another very important and known curbs formation included in the construction is quadrant and angle curbs. These curbs are complementary to making straight and radius curbs.

As they come in a variety of different angles and sizes, their incorporation has become rather common. Moreover, the foundation used to build these types of curbs make them stronger and durable. Quadrant blocks are known as ‘cheese’ as they can be cut to create angles that are less than 90°.
